One of the targets of solid state chemistry is development of highly enantioselective reactions. We have achieved several enantiospecific and diastereospeicfic photocyclization of isopropylbenzophenone derivatives by a cocrystal approach. Most of the reactions were accompanied with the decomposition of initial crystal structures, but a few single-crystal-to-single-crystal reactions were also found. In this Conference, we would like to report our recent research work about the correlation between the structure changes at molecular level and the crystal morphology changes at nanometer level during the reactions.
